A typical 40 page review has the following sections:

  • What It Is What It Does
  • Quality Concerns and What CL Tested For What CL Found
    • CL confirms that the amount stated is actually in the supplement
    • CL checks that there are no contaminates
  • Top Picks
  • Test Results by Product
  • What to Consider When Buying What to Consider When Using Concerns and Cautions
  • How Products Were Evaluated


  1. Typically the reviews will show the cost per unit of measure
    • (say 5 cents per 5,000 IU of vitamin D)
  2. Good review of the literuare as to the benefits and side-effects of each supplement
  3. They show the cost per unit meaure of a supplement
    • maximum cost of a supplement will often be 20X of the minimum cost
  4. They frequently update each review - popular ones are updated several times a year
  5. They have a 5 day free trial


  1. Suppliers must pay to have their products reviewed, so CL typically only reviews a fraction of what is on the market, and sometimes not the most popular products at that.
  2. They often consider bio-availability of the different products
    • e.g. Magnesium, Calcium, Omega-3, oil form of Vitamin D
  3. They do not seem to consider interactions (positive or negative) between supplements - examples:
    • Vitamin D and Calcium
    • Vitamin D and Omega-3
    • Vitamin D and Magnesium
    • Vitamin D and Resveratrol
    • Vitamin D and Vitamin K
  4. You can only subscribe to all of their reviews - you cannot buy an individual review
    • $48/year - with a discount for 3 year contract
